Abstract
The invention discloses a valve control tubular steam generator integrated type safety boiler, and belongs to a novel steam boiler safety boiler. By means of the method of combining the valve control technology and space partition, the boiler is formed by connecting valve control tubular steam generators in parallel, wherein each valve control tubular steam generator is composed of a plurality of boiler tubes with self-control water inlet valves at inlets and comprehensive anti-explosion valves at the outlets. By means of the partition integrated boiler, the boiler explosion energy and damage caused by the explosion energy can be reduced fundamentally, and the boiler running safety is improved. The boiler is simple and reliable in structure, low in manufacturing and running cost and high in economy and practicability.
Description
Technical field
The invention belongs to a kind of steam boiler pot body.Specifically: a kind of novel boiler safety pot body.
Background technology
In field of boilers, no matter current be the boiler pot body of which type, and as the jumbo high temperature pressure vessel of one, its brisance and harm are well-known.
In order to prevent the blast of pot body, current unique effective method is exactly install two " pressure limiting rapid exhaust " on pot body, is commonly called as safety valve.Its principle is: when pot inner pressure reaches set upper limit, rapid drainage opened by safety valve, forces pot inner pressure to decline, and blasts to ensure a pot body to be unlikely to hypertonia.But most accident in the past, the pot inner pressure during bursting of boilers, far below safety valve excretion opening pressure, safety valve is inoperative.In other words, safety valve can only ensure that superpressure explosion accident does not occur pot body, and fundamentally can not prevent boiler accidental explosion accident under regular operating pressures.
We also know, the energy of boiler pot body blast and the size of harm are put to death in two large factors: one is a pot body bulk; Two is the instant pressure of explosion time.Volume huge explosion power is large, and the little brisance of volume is little; The instant pressure of explosion time is also like this.
At the volume neither changing pot body, under not reducing again the prerequisite of boiler working pressure, can effectively control the energy of pot body explosion time, fundamentally eliminate or greatly alleviate a pot harm for body explosion accident?
Valve keyholed back plate shape steam generator integrated form safety cooker body is exactly a comparatively complete solution.
Summary of the invention
1. the basic structure of valve keyholed back plate shape steam generator integrated form safety cooker body
The present invention uses valve-gating technology to separate with space the method combined: pot body space is divided into the little space of independence that several are isolated with explosion-proof valve, each little space is made up of a valve keyholed back plate shape steam generator, is then got up by several such separate unit integrated combinations.Its profile is as water-tube boiler pot body general at present.Both many boiler tubes 3 lower inlet had been adopted to be connected in parallel to the integrated type boiler body of steam convergence house steward 5 with the valve keyholed back plate shape steam generator of comprehensive explosion-proof valve 4 with automatic control water inlet valve 2 upper end outlet, as shown in drawings.
2. security performance of the present invention and subtract danger principle
In the present invention, the automatic control water inlet valve 2 of boiler tube 3 lower end series connection and the comprehensive explosion-proof valve 4 of upper end series connection, be divided into relatively independent unit pot body.If a unit is blasted, comprehensive explosion-proof valve 4 upper end and automatic control water inlet valve 2 lower end self-closed, blast can not involve other unit and house steward 5 of confluxing; Meanwhile, comprehensive explosion-proof valve internal safety valve superpressure excretion.In other words: separate unit volume is little and isolated by valve, explode the little several times of the similar boiler of hazard ratio caused.
3. the difference of the present invention and traditional pot body and usefulness
From outward appearance, valve keyholed back plate shape steam generator integrated form safety cooker body, if automatic control water inlet valve 2 and the comprehensive explosion-proof valve 4 of removing boiler tube 3 two ends, duplicates with water-tube boiler pot body profile of the same type at present.That is: two kinds of pot body total measurement (volume)s are identical with heating surface area.Therefore there is no difference with the performance of current pot body of the same type and the thermal efficiency.
4. the operation principle of valve keyholed back plate shape steam generator and quality of steam in the present invention
The flow process that steam of the present invention produces is as follows:
A) initially intake
Because the hydraulic pressure of boiler water pump or economizer is higher than boiler tube 3 overpressure, automatic control water inlet valve 2 is opened, and water injects rapidly boiler tube 3, and air is discharged from comprehensive explosion-proof valve; Along with pressure in the injection boiler tube 3 of water raises, the water feed rate of automatic control water inlet valve 2, from being varied down to last closedown, completes initial water inlet.
B) steam is produced
Water after filling, under the effect of stove fire, temperature increases rapidly generation steam, and in boiler tube 3, pressure starts to raise, and when pressure in boiler tube 3 is greater than comprehensive explosion-proof valve 4 lower end one-way throttle valve setting pressure, high steam overflows in comprehensive explosion-proof valve 4; Overpressure declines subsequently, and automatic control water inlet valve 2 reopens, moisturizing in boiler tube 3; The speed of feedwater and inflow, by residue vapor pressure co-controlling in supplementing water pressure and boiler tube 3, are next exactly repeat aforementioned process.
This valve keyholed back plate shape steam generator be made up of automatic control water inlet valve 2, boiler tube 3 and comprehensive explosion-proof valve similarly is an electronic impulser.With regard to single, the steam that it exports is unstable; Overall situation is just different, because pot body is integrated with multiple steam generator.When the vapour source of multiple random instability is flowed to together, they also can complementaryly as electric pulse superpose, and form metastable vapor stream, are exported endlessly by house steward 5 of confluxing.Therefore it is equally as broad as long with the quality of steam of water-tube boiler of the same type.
In sum, the present invention, except above-mentioned newly-increased safety measure, is also configured with other safety precaution equipment of existing similar pot body.It is a kind of new type of safe pot body be worthy to be popularized.The space compartmented security measure of uniqueness of the present invention and valve keyholed back plate shape steam generator integrated type boiler body, be with a wide range of applications.It not only may be used for various production and boiler for domestic, even can also be used for nuclear power boiler, and even nuclear submarine boiler.
